It's not possible to choose the type or color of the fletching. Please consult the manual of your crossbow to identify which nock type you need and which length to choose. A "too short" bolt is always a problem - a "too long" one rather not.
matching point: screw-in point with 11/32 inch outer diameter
Make sure you do not fall below the minimum weight of a ready-to-shoot bolt for your crossbow if the manufacturer of your crossbow states a minimum weight in the manual.
